The electrochemistry of (tetraphenylporphinato)cobalt(II), (TPP)Co, and chloro(tetraphenylporphinato)cobalt(III), (TPP)Co"'Cl, is reported in methylene chloride solutions containing various concentrations of tetrabutylammonium chloride. The two-electron reduction of (TPP)Co"'CI or the one-electron reduction of (TPP)Co generates [ (TPP)Co']-, but these reversible electroreductions are followed by a rapid irreversible chemical reaction with the CH2C12 solvent to produce a a-bonded cobalt(II1) complex. Electrwxidation of (TPP)Co in the presence of C1-generates either (TPP)Co"'Cl or [(TPP)CO~~'CI~]-after abstraction of one electron and [(TPP)Co1"Cl]+ or (TPP)Co"'C12 after abstraction of a second electron. The [(TPP)CO~~CI]-/[(TPP)CO~~'CI~]-and [(TPP)CO~~'CI~]-/(TPP)CO~I~CI~ reactions occur at E, = 0.57 V (cyclic voltammetry, scan rate = 0.1 V/s) and E l j 2 = 0.63 V, respectively. (TPP)Co"'Cl is reversibly oxidized to [(TPP)Co"'Cl]+ at 0.90 V and to [(TPP)CO~"CI]~+ at 1.15 V in the absence of excess C1-. ESR, UV-visible, and thin-layer spectroelectrochemical methods were utilized to characterize the reactants and products of each electrode reaction. and a mechanism for the chloride-binding reactions and electrochemistry of (TPP)Co and (TPP)Co"'CI is presented.

“…While the spectra of the compounds just discussed are constant, this is not true of the spectrum of (Pc-GeO)z, the position of the broad, strong Ge-O-Ge asymmetric stretching band varying over a range of at least 864-899 cm-1. 20 It is thus not surprising that the position of the Ge-O-Ge band in (hpGeO)z also varies. Here the range found so far is from 878 to 911 cm-1, the low value being for a sample prepared by the condensation of hpGe(OH)2 in a nitrogen atmosphere (the product of a dta experiment), and the high value being for a sample prepared by the condensation of hpGe(OH)2 in 1 -chloronaphthalene and stored for 16 months.…”
